Top 14 Factors Affecting Strength Of Concrete ...

For concrete that has to be compacted by a vibrator, a lower water cement ratio may be used. The maximum strength is derived at w/c = 0.4. When the water cement ratio is less than 0.4, there is improper consistency and workability of the cement and honeycombed structure.

11 Factors that can Affect the Strength of Concrete

2 天前 · Compaction of concrete increases the density of the concrete because it is the process in which air voids are removed from freshly placed concrete which makes the concrete compact and dense. The presence of air voids in concrete greatly reduces its strength .Approximately 5 % of air voids can reduce the strength by 30 to 40 %.
